Final answer:
The centripetal acceleration of the Moon is influenced by Earth's gravity. Earth's gravitational force causes the Moon to orbit Earth.
Step-by-step explanation:
The centripetal acceleration of the Moon is influenced by Earth's gravity.
Earth's gravitational force causes the Moon to orbit Earth. The centripetal acceleration of the Moon differs by less than 1% from the acceleration due to Earth's gravity.
This agreement is approximate because the Moon's orbit is slightly elliptical, and Earth is not stationary.
